退出后C#控制台应用程序仍在内存中 – 异步Web服务

我是C#和.Net的新手.我的老板让我使用Web服务使用异步回调创建一个计时器.我实际上创建了它,并让它工作,但每当我关闭控制台应用程序窗口时,Web服务仍在运行.当我重新运行应用程序时,它从0开始计数器,但是来回跳转到前一次运行的数字(仍然在记忆中).

mainMethod()每10秒将数字增加1,monitorMethod()读取该数字,并返回一个字符串.

如何停止Web服务,并在每次关闭控制台窗口时将计数器重置为0？

我希望这是有道理的！提前致谢！

这是我的代码.

网络服务：

public class Service1 : System.Web.Services.WebService
 {
    private int iTotal;
    private int iCurrent;

    [WebMethod]
    public void mainMethod()
    {
        iTotal = 42;
        iCurrent = 1;
        Application["iTotal"] = iTotal;
        Application["iCurrent"] = iCurrent;
        // sleep 10 seconds
        while (iCurrent <= iTotal)
        {
            Application["iCurrent"] = iCurrent;
            iCurrent++;
            System.Threading.Thread.Sleep(10000);                
        }
    }

    [WebMethod]
    public string monitorMethod()
    {
        iCurrent = int.Parse(Application["iCurrent"].ToString());
        iTotal = int.Parse(Application["iTotal"].ToString());
        if (iCurrent <= iTotal)
        {
            return iCurrent + " of " + iTotal;
        }
        else
            return "DONE";
    }
  }
}
